K-pop<\/a> sensation ATEEZ\u2019s latest music video, \u201cBAD<\/a>,\u201d has been receiving all kinds of attention. The song is an earworm \u2013 extremely catchy. It\u2019s hard to avoid singing the chorus: \u201cShe’s so bad, bad, bad, bad, bad, bad, bad (Ooh, wee) \/ She’s so bad (Chk-chk-chk-cha), ayy (Run it all night solo) \/ Bad, bad, bad, bad, bad, bad, bad (Ooh, wee) \/ She’s so bad (Chk-cha, chk-cha), yeah (Run it all night solo).\u201d It also doesn\u2019t hurt that Hollywood\u2019s rising starlet \u2013 and hardcore ATINY (name for ATEEZ fans) \u2013 Chase Infiniti stars in it. She gets to act opposite her favorite group, which comprises Hongjoong, Seonghwa, Yunho, Yeosang, San, Mingi, Wooyoung, and Jongho. She is especially excited to star opposite her \u201cbias,\u201d San.<\/p>\n San (full name: Choi San), the 26-year-old muscular South Korean artist, has been going viral<\/a> since the music video dropped. During one of the choruses, he is front and center doing the signature choreography, which has been getting a lot of attention. Fans have nicknamed that portion of San\u2019s choreography near the end \u201cLet\u2019s All Die,\u201d with many overlaying that routine onto their panicked, stressed, or passed-out faces. At one point, there are a few videos that express San being the \u201cgay awakening\u201d for several South Korean men who identify as \u201cstraight.\u201d As of today, the music video, released on June 26, has over 22 million views, with San\u2019s portion being the \u201cMost Played.\u201d<\/p>\n Just two days later, the group appeared on the music show SBS\u2019s Inkigayo as part of their promotional tour. Again, San, this time in a white tank, wowed the crowd during his moment and became the \u201cMost Watched\u201d for that video with 1.5 million views. While the other videos did not offer the timestamp viewer information, fan cams and edits of San\u2019s dance began popping up, going viral yet again. It\u2019s difficult to avoid seeing him on the algorithm if one follows general K-pop content.<\/p>\n ATEEZ\u2019s company, KQ Entertainment, knew what was going on and released a demo version of San’s choreography that did not include the popular segment. San offered a high-energy, fast-paced move rather than the slow, sensual part.<\/p>\n It\u2019s not the first time San has gone viral, attracting new followers to the ATEEZ fanbase. The vocalist is part of the \u201cDemon\u201d line from ATEEZ (which also includes Hongjoong and Seonghwa), which means their performance is strong, emotive, captivating, and demonic \u2013 it almost feels possessed. Several of his performances have gone viral, particularly ones where he\u2019s practically shirtless (See \u201cHala Hala\u201d). He went so intense once that he broke his microphone. During the 2024 MAMA Awards, San left everyone in shock with his ending fairy, which featured him taking off his jacket as he walked away, revealing a giant (fake) tattoo.<\/p>\n He\u2019s also gone viral for the group\u2019s previous music video, \u201cIce On My Teeth,\u201d from the EP GOLDEN HOUR: Part 2. The two \u201cMost Watched\u201d moments were the one-second clip of San shirtless, looking up, and the one of San in a suit and glasses, dancing to the chorus.<\/p>\n He is often described as a person\u2019s \u201cgateway\u201d to ATEEZ or to K-pop in general. Fans often notice his charismatic stage presence and sexual appeal in music videos. Though he has many fans who favor him, he is often the first bias for fans before they learn more about the other members. San has complained<\/a> over the years about fans telling him, \u201cI got to know ATEEZ because of you.\u201d \u201cI became a fan because of you.\u201d When he asks them who their bias is, they stare blankly at San, refusing to answer, letting the time run out before moving on. He says during one live, \u201cI did not make this up. It is real. Really, I get this a lot in one day.\u201d<\/p>\n These interactions have been documented, as San often asks fans about their biases (and whether it was him), leaving them flustered \u2014 because he is not. Some tell San he\u2019s their mom, sibling, partner, kid, or someone else\u2019s favorite. He then trolls them afterward, jokingly.<\/p>\n ATEEZ gained an influx of fans after Netflix\u2019s KPop Demon Hunters premiered, with comparisons between the real-life group and the fictional demonic K-pop group, Saja Boys. One character, ABBY, was often compared to San, as they both have the same physique. More ATEEZ videos began appearing in social media algorithms that followed Kpop Demon Hunters and Saja Boys content. Fans of the film began watching clips of ATEEZ, with San at the center. They just wanted to research them further, finding themselves digging deeper into the fandom.<\/p>\n SEOUL, SOUTH KOREA – FEBRUARY 5: Members of ATEEZ Yunho, Seonghwa, San, Yeosang, Hongjoong, Wooyoung, Jongho and Mingi attend the press conference for the group\u2019s 13th mini album \u2018GOLDEN HOUR : Part 4\u2019 at Fairmont Ambassador Seoul on February 5, 2026 in Seoul, South Korea.

Videos of ATEEZ, particularly San’s fancams, began appearing in her feed. Her friends, who were ATINYs, began sending her more clips of San, and she \u201cfell down the rabbit hole.\u201d<\/p>\n She became enamored with San and decided to attend an ATEEZ concert, her first K-pop concert ever. She recalls, \u201cAs a baby ATINY, I was fully committed to him. The way he loves his body and his obvious good looks were what got me at first, but the more I watched, the more I fell in love with the songs and his voice. I purchased his jersey and other merchandise before the IN YOUR FANTASY tour and had him as my [phone] background.\u201d<\/p>\n After the concert, she found herself drawn to another member and wanted to get to know them better. She learned about all eight members and says she\u2019s OT8 (meaning \u2018One True 8\u2019 that represents loving all eight members together) but is now a Hongjoong bias. She clarifies, \u201cI\u2019m a Hongjoong bias with seven wreckers, because, after all, \u20188 Makes 1 Team\u2019 (ATEEZ\u2019s core motto).\u201d<\/p>\n SEOUL, SOUTH KOREA \u2013 DECEMBER 20, 2025 – ATEEZ San attends the blue carpet event of the 2025 KBS Entertainment Awards at KBS Hall, Yeouido, Seoul.

Since the release of ATEEZ\u2019s GOLDEN HOUR PT. 5 and the music video for \u201cBAD,\u201d San has gained over 1 million more Instagram followers, reaching 11.4 million and slightly surpassing the group\u2019s official Instagram by 200k. He\u2019s also been seen appreciating the love he\u2019s received, responding to fans by \u2018liking\u2019 their posts or commenting. He posted a note on ATEEZ\u2019s messaging app<\/a> expressing his gratitude for the love and for fans enjoying their own version of the viral dance.<\/p>\n Hongjoong said on a recent livestream<\/a> that the group is grateful for the attention they are getting, especially with San. He says, \u201cSan worked incredibly hard preparing for this, so seeing so many people recognize that makes me really proud as someone who’s been watching him up close. And it\u2019s just really nice seeing our song everywhere too.\u201d<\/p>\n Many of those who were drawn into ATEEZ because of San have remained San biases, including Inifiniti. Not just for his good looks, strong vocals, and charismatic performances, but also for his pretty funny content, especially when trolling the fans<\/a>.<\/p>\n
